Converter is an interface describing a Java class
that can perform Object-to-String and String-to-Object conversions
between model data objects and a String representation of those
objects that is suitable for rendering.

Converter implementations must have a zero-arguments public
constructor. In addition, if the Converter class wishes to have
configuration property values saved and restored with the component tree,
the implementation must also implement StateHolder.

If any Converter implementation requires a
java.util.Locale to perform its job, it must obtain that
Locale from the UIViewRoot
of the current FacesContext, unless the
Converter maintains its own Locale as part
of its state.

Method Summary

java.lang.Object

getAsObject(FacesContext context,
UIComponent component,
java.lang.String value)
Convert the specified string value, which is associated with
the specified UIComponent, into a model data object that
is appropriate for being stored during the Apply Request
Values phase of the request processing lifecycle.

java.lang.String

getAsString(FacesContext context,
UIComponent component,
java.lang.Object value)
Convert the specified model object value, which is associated with
the specified UIComponent, into a String that is suitable
for being included in the response generated during the
Render Response phase of the request processing
lifeycle.
